“IT COSTS NO MORE TO GROW THE BEST” 
Our list of iris is comparatively small. We do, however, list practically all the varieties of real importance, and 
satisfactory growing qualities. 
It has always been our policy to offer only the best varieties. After the customer's initial investment the cost of 
growing is no greater than that of the commonest sorts. 
Iris are quite different from other flowers and shrubs. When you buy a rose or a flowering bush you are re- 
warded only by larger growth from season to season, and have no increase. But when you buy an iris this year, 
the seasons will give three or four times as many, and in a few years you will have a grand display. Also remember 
that few flowers will stand hardships as well as iris.

GENERAL INFORMATION 
The iris described in the following pages are mostly bearded 
iris. The range of color is unbelievably large, even though all the 
blue, pinks and reds contain some violet. The yellows range from 
palest primrose to rich gold. 
The standards are the three upstanding petals, the falls are 
the three lower petals. 
A bi-color is an iris that has standards of one shape and falls 
of another, usually considerably darker. A blend, as the name 
indicates is a suffusion of several colors. A plicata is a light 
colored iris, the edges of which are flushed, lined or dotted with 
color. A self carries the same shade throughout the whole flower. 
A variegata has yellow standards and reddish-brown falls.
